These ions empower the crystal to amplify mild on the laser wavelength by way of stimulated emission, when Strength is supplied into the crystal by using absorption of pump light (�?optical pumping

为了使激光器有效运作,需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热,防止热透镜效应或断裂。

作为工业上使用较多的都是高掺钇铝石榴石,也就是说掺入不同的元素来达到不同的效果;作为工业激光,关注以下性能:

GWU features all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) having a wide variety of requirements. In addition to the properly-founded resources, revolutionary crystals with exceptional Homes like Yb:CALGO can open up new horizons for demanding laser applications. It doesn't matter regardless of whether unique parts for R & D purposes are necessary or Expense-productive figures in little, medium or massive batches with in-time shipping for that production line are required: GWU’s committed assistance helps you to locate the greatest core factors for the application.

A superior floor good quality is certainly critical. Requirements of floor flatness will often be much better than . This will help to stop both scattering losses and wavefront distortions which can degrade the laser's beam high-quality. In addition, scratch and dig specs

g. a thin disk. As An additional case in point, Q-switched lasers access the next population density in the higher laser stage and therefore are therefore a lot more delicate to quenching effects and Vitality transfer procedures; for that reason, a reduce more info doping density is often appropriate for these products. For prime-ability lasers, reduced doping densities will often be utilized to Restrict the density of warmth generation, Despite the fact that slender-disk lasers work very best with really doped crystals. A lot of laser products will not get to the full effectiveness potential for the reason that these particulars have not been effectively worked out.

Laser modeling and simulation can be employed to reliably determine the the best possible crystal dimensions, doping density And perhaps values of added parameters.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Those surfaces that happen to be passed with the laser beam are Commonly possibly oriented at Brewster's angle or have an anti-reflection coating.

GWU-Lasertechnik has over thirty years of expertise in distributing laser crystals. Choose GWU to gain from our huge understanding and in-subject working experience!

With That idea, a single does not need to have an extra saturable absorber crystal, making sure that one could make a lot more compact Q-switched laser setups with lower interior parasitic losses. Having said that, unwelcome Unwanted side effects can also take place, for example acquiring undesirable valence states of the involved ions or Vitality transfers.

激光晶体(laser crystal),可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
